What is a Casino?

A casino is a public room or building where gambling games are played. The vast majority of the entertainment at casinos comes from gambling games, with slot machines, blackjack, craps and keno raking in billions of dollars every year.

A Casino’s Main Goal is to Keep the Players Happy and Addicted

There are a number of things that casinos do to keep their patrons satisfied and addicted to their gambling. For one, they give gamblers free food and drinks. Those that make large bets are also offered free transportation and luxurious living quarters, which helps to keep them coming back.

They also use chips instead of real money, which makes it less likely that the player is concerned with their actual winnings and losses. They may also put ATM machines in strategic locations.


The main way a casino keeps its patrons safe is by hiring highly skilled, trained employees who know how to spot cheating and other irregularities. Dealers and pit bosses are trained to look for obvious cheating, like palming, marking or switching cards or dice.

Other aspects of casino security are more subtle. Patterns in the way dealers shuffle and deal their cards, where the betting spots are on the table, and how a player reacts and moves are all easy to spot by security personnel.

In addition, elaborate surveillance systems offer a high-tech “eye-in-the-sky” that allows security staff to watch the entire casino at once. They can change windows and doorways to focus on certain suspicious patrons, and video feeds are recorded so if someone does something unusual, the casino can look back at the tapes later.
